PanaChart is a PHP class for online charts creation using PHP scripting language and the GD image manipulation library. It makes it easy to plot several types of charts with less then 10 lines of code. PanaChart is suited for any scientific or business web application.
The source code of the library is very compact and resides in a single file, which considerably reduces the load, parsing and execution time. The average size of a generated PNG image is less than 2 KB and the average creation time is 20 milliseconds. All these features makes PanaChart suitable for realtime graphic charts production. See the online demo or the examples page.
Panachart requires PHP 4 scripting engine with GD 2 image library support enabled.
- Bandwidth friendly, the average image size for a 450*250 image is around 2K

- Can output to a file or directly to an HTTP stream
- Supports several plot types: bars, lines, dots, areas, step, impuls

These files were created as I needed a slightly faster way of producing graphs than other options available on the web. Other PHP scripts using the GD Libraries seem to be so complicated they take too long to draw and display on a poor performance machine.
Set of Php Classes for creating charts and graphs. It supports more than 18 types (linechart, piechart, barchart, radarchart,

This class allows you to supply the values of the user quota (as you might gather from the file system, imap, or your own database driven system) and output them as a nice graph, or as text. The colours of the graph are definable, and you can also change whether you have it as a flat pie chart or a 3D pie chart. This was designed to mimick the disk space graph used on Windows.
